How Speakers Work

What is the principle of electromagnetism?

• The physical phenomenon of the interaction of the magnetic field formed by electric currents and the external magnetic fields.

• The principle of electromagnetism is the study of static electricity

• The principle of electromagnetism is the process of converting sound waves into electrical signals

• The principle of electromagnetism is the study of the behavior of light in magnetic fields

What is the role of frequency in sound?

• Frequency determines the texture of the sound.

• Frequency determines the color of the sound.

• Frequency determines the temperature of the sound.

• Frequency determines the pitch of the sound.

How does amplitude affect the sound produced by a loudspeaker?

• It affects the volume of the sound produced.

• It affects the texture of the sound produced.

• It affects the color of the sound produced.

• It affects the taste of the sound produced.

What are the key components involved in the conversion of electrical signals to sound in a loudspeaker?

• diaphragm, voice coil, magnet, and cone

• battery, resistor, capacitor, and inductor

• keyboard, mouse, monitor, and CPU

• paper, ink, printer, and scanner

How does the principle of electromagnetism apply to the functioning of a loudspeaker?

• The magnetic field generates electricity to power the speaker

• The electric current causes the speaker to heat up

• The electric current creates vibrations in the speaker cone

• The electric current interacts with the magnetic field to produce sound waves

What is the main energy transferred in a loudspeaker?

• Converts sound energy into electrical energy

• Converts electrical energy into sound energy

• Generates a magnetic field

• Produces a compression wave

What is the main part of a loudspeaker that is connected to the moving coil?

• Cardboard cone

• Permanent magnet

• Diaphragm

• Tube

Can a loudspeaker be used as a microphone?

• No, it is not possible

• No, it is not recommended

• Yes, but it is not very effective

• Yes, it is very effective
